Inno Setup 在安装时在目标目录中创建的临时 tmp 文件

Question

One of my customers reported that my app installer creates a temp file like is-XXXXX.tmp in the {app} directory, which are identified by anti-virus app as malware. The temp file would only live for a very short time, so I can't make a copy of it. My customer ask me to send him a copy of the temp file to make sure there is no harmful code inside it. Is there any method to copy this temp file out on installation? Thanks!

Answer 1

When Inno Setup is extracting files to their destination folders, it always does that first by storing them to the file names like is-XXXXX.tmp . Only then, it renames them to their actual file names.

So all those files are actually the files that your customer has in the destination folder once the installation completes.
